And the simple question is - Should a gambler be afraid of losing money to gambling? Why not simply stay away from gambling then?

I later tried to find out what actually happened and discovered the dude had only put around $0.7 on the bet and won around $3.5 (amount not enough to even buy him a snack and a bottle of bear), this was the reason he was not happy and wished the bet ended in a loss 😁.

I later in the chat asked him why didn't he bet a bigger amount of money like atleast between $20 and $50, any of this amount would have given him a nice total win amount from $100 and above, he responded saying he initially wanted to bet $15, but he was afraid of losing this money, coupled with the fact that he wasn't also sure the bet would win, and I then asked him, why is he now angry for winning a small amount of money when it's completely his fault? And what is the essence of gambling in the first place when the fear of losing money outweighs the desire to win big amount of money?
